HC Deb 26 November 1979 vol 974 c502W
Mr. Hardy

asked the Minster of Agriculture, Fisheries and Food what representations have been received on the design and diameter of pipes used in field drainage schemes; and what consideration he is giving to these.

Mr. Wiggin

Consultations have taken place with the trade associations on the designed data for field drainage and ditching pipes. The comments received are being considered in conjunction with the research which is in progress at the Ministry's field drainage experimental unit.
